Thanks Chookie, but I did say Cyathea not Dicksonia which is the 'pineapple'
you stated. Cyatheas need a root ball!
Not too many native gardeners out there eh?

How much root bal should be kept on these tree ferns? What would the
minimum be. I have a friend who wants to get rid of 4 that are 4
meters
high and have about 18-20cm trunks.
I live in the Hawkesbury region and the ferns are coming from Kurrajong
heights.

Depends on species -- there is one type where you can just chop the crown
off
and plant that, like a pineapple. I'd ring the local Australian Plants
Society group or a local specialist native or fern nursery for advice.
